keeps saying it cant find 'num_teachers' even though that's the name of the function?

also if my code is wrong please help too, thanks so much :)

teachers.py 
# The dictionary will look something like:
# {'Andrew Chalkley': ['jQuery Basics', 'Node.js Basics'],
#  'Kenneth Love': ['Python Basics', 'Python Collections']}
#
# Each key will be a Teacher and the value will be a list of courses.
#
# Your code goes below here.
def num_teachers(dict1):
    for key in dict1.keys():
        return int(keys)

Is the question asking you to return how many teachers there are? if so, you need to find how many keys there are in the dictionary(remember the len())function). The for loop is not needed. Also, I don't think you would ever want to put a return statement in a for loop.

Try this, let me know if this works.

def num_teachers(dict):
    return len(dict.keys())
